Telegraphenamt hosts conferences, board meetings, product launches, gala dinners and company parties, from 20 guests at a long table to 400 in theatre rows and up to 652 at a standing reception. The hotel stands at Monbijoustraße 11 in Berlin Mitte, next to Museum Island, and combines 97 rooms and suites, restaurants and bars with its event spaces in one address.
Seminars and company events
The largest room, the Kutscherhof, covers 611 m² under a fully glazed roof with exposed steel beams and oak parquet. It takes 400 in theatre rows, 240 in classroom layout, 300 at banquet tables and 150 in cabaret style. For a mid-sized conference, the Postsaal (210 m²) seats 120 in rows and the Galerie (176 m²) 90. The Wohnzimmer, at 166 m², suits a board meeting or workshop with up to 60 in rows or 34 at classroom tables. All four are on the ground floor, which makes it simple to pair a plenary with breakout rooms. The venue presents conferences for up to 300 delegates and parties for up to 600 guests as its main formats, and a cinema room, the Kino, is also listed for screenings, without capacity figures.
Rooms and capacities
Standing capacities run to 652 in the Kutscherhof, 224 in the Postsaal, 188 in the Galerie and 177 in the Wohnzimmer. Banquet figures are 300, 100, 50 and 30 respectively. The ROOT restaurant covers 479 m², and the ROOT Bar, at 272 m², takes 200 standing. In the basement, the Rohrpostbar (133 m²), named after the pneumatic tube post, holds 200 standing or 30 in rows. A second site, the Forum an der Museumsinsel, adds the Dieselhaus, with 345 m² on the ground floor, 235 m² upstairs and a 153 m² terrace for a banquet of 260; the café L'OUI, with 20 at a table, 40 in rows or 60 standing; Petit Bijou, with 174 standing; and outdoor space in the Forum itself.
Accommodation
The hotel has 97 rooms, maisonettes and suites, from 21 m² to 140 m², enough to house a board, a leadership team or a sales kickoff on site. It holds two Michelin Keys in the 2026 guide and a rating of five stars and 92 points in the Falstaff hotel guide. A gym is part of the facilities.
Catering
Food and drink come from the hotel's own outlets: the ROOT restaurant and ROOT Bar, the café L'OUI and the bars, where trained mixologists prepare the cocktails. Coffee breaks, business lunches, banquet menus and standing receptions are served by the in-house teams rather than an outside caterer.
History and setting
The building was the main telegraph office of Berlin, built in the early 20th century to handle the city's telegraph and pneumatic post traffic, and has been restored as a hotel. Its name, the Rohrpostbar and the steel and glass structure of the Kutscherhof keep that working past visible. Monbijou Park and the Spree lie across the street, and the museums of Museum Island are a few minutes on foot.
Getting there
Oranienburger Straße S-Bahn station, on the S1, S2 and S25 lines, is a few minutes away on foot. Hackescher Markt, with S-Bahn and tram connections, is a short walk south and two stops from Berlin Hauptbahnhof for long-distance trains. Berlin Brandenburg Airport (BER) is around 40 minutes by train or car.
